    Given the growing number of patients receiving direct oral anticoagulant (DOAC), patients requiring rapid neutralization is also increasing in case of major bleedings or urgent surgery/procedures. Idarucizumab is commercialized as a specific antidote to dabigatran while andexanet alfa has gained the Food and Drug Administration and the European Medicines Agency approval as an oral anti-factor Xa inhibitors antidote. Other antidotes or hemostatic agents are still under preclinical or clinical development, the most advanced being ciraparantag. DOAC plasma levels measurement allows to appropriately select patient for antidote administration and may prevent unnecessary prescription of expensive molecules in some acute clinical settings. However, these tests might be inconclusive after some antidote administration, namely andexanet alfa and ciraparantag. The benefit of laboratory monitoring following DOAC reversal remains unclear. Here, we sought to provide an overview of the key studies evaluating the safety and efficacy of DOAC reversal using the most developed/commercialized specific antidotes, to discuss the potential role of the laboratory monitoring in the management of patients receiving DOAC specific antidotes and to highlight the areas that deserve further investigations in order to establish the exact role of laboratory monitoring in the appropriate management of DOAC specific antidotes. Anticoagulation monitoring and specific reversal agent targets DOAC: direct oral anticoagulant; dTT: diluted thrombin time; ECA: ecarin chromogenic assay; ECT: ecarin cloting time. Display omitted •Antidotes for direct oral anticoagulant (DOAC) reversal have been developed.•The role of laboratory monitoring in DOAC reversal using antidotes is unclear.•Dabigatran level prior to idarucizumab could predict reversal outcome.•Oral FXa inhibitor levels cannot be easily measured following andexanet alfa.•DOAC measurement using commercialized assays is not possible after ciraparantag.
